Fermilab Calls For Code Crackers 392

Posted by kdawson
from the finding-patterns-where-none-may-exist dept.
atrocious cowpat passes along a call for help from symmetry magazine, the joint publication of Fermilab and SLAC, noting: "Could be just plain gibberish, it could be something like those wonderfully weird letters to the Mount Wilson observatory, or it could be a message from aliens who just happened to have gotten their hands (tentacles/exoskeleton) on a fax machine." "A little over a year ago, the Fermilab Office of Public Affairs received a curious letter in code (4.4-MB image here). It has been sitting in our files all that time and we haven't had much of a chance to look into breaking the code, nor are we particularly expert at this!"

      To be able to decrypt a message it is usually necessary to know the context to where it belongs. Without context it's hard.

      And is it really a message, it can be other things too:

      1. A data sampling done by hand with two samplings, the first has three alternatives the second has two. The code in the middle is just thrown in for good measure by a joker.
      2. It's someone's way to compose music. The first part is for a simple instrument with three tones, the last part is another instrument with two alternatives (bongo drums?). The middle part is just markers used to remind the performers about what to sing.
      3. Someone's idea of a prank to pull.

    Three "stanzas" maybe.

    Starting with the "middle" stanza, that appears to be some sort of "key" perhaps. Each of the different symbols correspond to a different hexadecimal digit.

    In the first stanza, each grouping of lines has 1, 2 or 3 lines.

    In the last stanza, each group of lines is only 1 or 2 lines.

    Maybe the last stanza is binary?

    And maybe the first stanza is base 3?

    Anyone else care to wager a guess?

              (trying to move the interesting stuff to the top) The top and bottom part of the code code the same data. The little indentation at the beginning of the line is important and means that the previous line continues. The indentation in the bottom bottom part is of, perhaps because of writing conditions. The top part consists of five trinary numbers of lengths 29, 46, 14, 14, 8 digits. The bottom part consists of five binary numbers of lengths 75, 110, 37, 36, 8 digits. My best transcription, probably with errors:

                The first and last parts *DO NOT* look like terniary and binary to me.

                Instead, they look like an RLL encoded pattern, similar to what you'd see on a hard drive. Maybe NRZI.

                In fact, the first looks surprisingly like (1,3) MFM RLL.
                Also reminds me of the old Apple Floppy drive "between any two ones there can only be a maximum of one zero" data writing rule.

                We've mostly solved it further down the thread. The top section is in ternary (with 0 replaced by |||), 000-space, 001->a, 002->b, etc. It's strangely wrapped: the spaces and non-spaces at the beginnings and ends of lines count. It says "FRANK SHOEMAKER WOULD CALL THIS NOISE".

                The second part we haven't deciphered yet. It's possible that we'd need a Fermilab insider for this.

                The third part is RLL. Once you decode the RLL (number of | between consecutive ||), you get the same code as part one, which says "EMPLOYEE NUMBER BASSE SIXTEEN", or so I've been told. This suggests that at least one part of the puzzle requires help from Fermilab people.

                My uninformed guess is that once we solve the middle section, we'll get someone's name. His or her employee number at Fermilab spells something out in base 16, a coincidence which Frank Shoemaker would call "noise". Another possibility is that the middle section is hex-encoded employee ID numbers, which would mean that we can't solve it.

      Another possibility: a blank represents a 0, a mark indicates a 1, giving us binary. This fits better with the hex in the middle of the page, since three binary go into one hex. The symbols don't make any sense, however, so if that's a key, then it's going to just translate it into another code.

      If I weren't at work, I would try translating the hash marks into their hex equivalent, storing that, then translating the hex to the symbols that were given and storing that separately. The symbols may mean something to someone other than me (some of them look hebrew, but some of them definitely aren't; perhaps astrology symbols or something else?), or it may be that the key in the middle is a red herring and that the hex itself codes for something (ascii being the most likely generally, although a quick glance seems to indicate that some of them would code for non-display characters).

      Most likely a hoax all things considered. A (accidentally?) clever hoax, considering the hex in the middle and the many interpretations of the vertical lines, but most likely a hoax nonetheless.

B is a minus sign. 6 is the negation sign. in logical notation. 7 is the greek letter phi, used for a number of things [wikipedia.org], most importantly the golden ration. D looks familiar but I can't place it right now, same with 4.

      I'm thinking the last stanza is also base 3, with digits then represented in unary, but with || indicating a division between the base 3 digits.

      So || | | || is "2" with a separation marker on each end.

      This would put an anomaly at the end of the second line which could be interpreted as the || being broken across the two lines (so the second line would end with 3 and the third line would start with 3).

        I think that's an interesting approach. Statistically speaking, if | and || would be two different symbols, the chance that one of them would never appear consecutively would be zero. As such, I agree that the || is probably a demarcation. Furthermore, the last character at the end of each line of the last stanza is probably also a demarcation, drawn before actual code series was written out. The reason I say that is because the last characters are the only ones that are actually beneath each other - the s

    There are 113 symbols, each of which is either 1, 2 or 3 strokes. So it is essentially a 113 digit base 3 number.

    This limits the amount of information that the message is trying to pass.

    For example, using base 26 - all the letters - means we could convey the same information in ??? digits.

For instance, on the left hand side of both code blocks some of the "first" ticks don't align with other first ticks. There are also some places in the code where the vertical alignment is ambiguous.

    But the whole thing is scattered enough that it comes out like more of a one handed improv or approximation of Steve Reich's "Clapping Music". [youtube.com]

    The bottom section is less rhythmically active, but sounds more "even", kind of "rock and roll" ish.

    The middle part is a dull cipher, similar to Nugsoth. [fontstock.net]

    That's all I've got.

    1. Four DNA characters: A, C, G, T
    2. Four character sequences: |, ||, |||, (space)
    3. Determine character mapping.
    4. ...
    5. Velociraptor.
  • Seriously though, what the frack are these symbols? I think most of them fit into extended ascii, but not D and 4 (at a minimum, i'm basing this on knowledge from 20 years ago...)

    See those three symbols on their own? An S, followed by a triangle, followed by a three-pronged character? Well if you look in the table directly above those three characters, you'll see that the triangle translates to F and the three-pronged character translates to C, giving S.F.C. altogether.

    while it may not be terribly relevant to the solution, it's worth noting a few oddities about the author's writing style. first of all, the second set of vertical lines is likely to be read right to left. notice how well justified the right side of the message is, while the left side terminates at various locations. we also know he writes the individual clusters from left to right based on the strokes left at the bottom of the bars.

    secondly, i assume the author is writing with a felt tip pen and is transcribing this from another source. notice how some bars will have a larger dot at one end or the other. i postulate that the author has set down his pen and is checking another sheet to determine what to write, while his felt pen bleeds a little too much ink onto the paper. this, however, doesn't happen with a ball point pen. perhaps this will be of assistance in determining the order strokes were written in, giving us some insight into the author's intent.

    thirdly, notice that the author writes the number 0 with a slash through it, but not the number 7 with a dash through it. i'm not an expert on handwriting identification, but certain groups will often be more keen on the selection of particular stylistic numbers, so this may help us to understand something of the author's background.

    finally, note that many of the chars used in the second section are letters from other char sets. the letter i is obvious to the english readers, but less apparent is the instance of one that looks suspiciously like a greek capital phi. also, several bear a striking resemblance to chars that appear in a masonic cypher alphabet. http://www.odr.org/anonymous/fam-code.htm [odr.org] can the other chars be identified as belonging to specific alphabets?

    The first part is ternary, with 3 substituted for 0. It's somewhat miswrapped, but it appears to say "FRANK SHOEMAKER WOULD CALL THIS NOISE".
